Translation of the verse 67 from Surah Az-Zukhruf : Number of verses 89 - - page 494 - Part 25.
Friends on that Day will be foes one to another except Al-Muttaqun (pious - see V. 2:2).
Close friends, that Day, will be enemies to each other, except for the righteous
(43:67) On that Day even bosom friends shall become enemies to one another, all except the God-fearing. *59
*59) In other words, only those friendships will remain unaffected which are based on righteousness and piety in the world; alI other friendships will turn into enmities, and those who are cooperating with one another in deviation, tyranny and wickedness today, will on the Day of Resurrection, put the blame on others and try to escape. This subject has been treated repeatedly at many places in the Qur'an so that every person in this very world may fully realize with whom it would be beneficial for him to cooperate and with whom it is harmful.
